Researchers show that Sirt3 enzyme decreases in skeletal muscle of diabetes patients

Researchers at the Joslin Diabetes Center have shown that an enzyme found in the mitochondria of cells is decreased in the skeletal muscle of those with diabetes, a finding that could lead to the development of drugs to boost the activity of this enzyme in an effort to fight the disease.

Scientists identify molecular pathway that plays a key role in stress-related DNA damage

Working closely with a team of researchers from Duke University, scientists from the Florida campus of The Scripps Research Institute have helped identify a molecular pathway that plays a key role in stress-related damage to the genome, the entirety of an organism's hereditary information.

Stem cells of oral mucosa stay young, says Tel Aviv University researcher

While highly potent embryonic stem cells are often the subject of ethical and safety controversy, adult-derived stem cells have other problems. As we age, our stem cells are less pliant and less able to transform into the stem cells that science needs to find breakthrough treatments for disease.

Scientists identify brain-circuit defect that triggers absence seizures

Researchers at the Stanford University School of Medicine have identified a brain-circuit defect that triggers absence seizures, the most common form of childhood epilepsy.

ARUP Laboratories introduces Affymetrix CytoScan HD Array

ARUP Laboratories, a leading national clinical and anatomic pathology reference laboratory and a leader in innovative laboratory research and development, is pleased to introduce its newest SNP-based microarray technology, the Affymetrix CytoScan HD Array.

Risk of Parkinson's disease increases with traumatic brain injury and exposure to pesticide paraquat

Traumatic brain injury has entered the public's consciousness as the silent, signature wound brought back by many of our military warriors from Iraq and Afghanistan. But such injuries don't only happen in warfare, they happen to civilians too. Think car crashes, a slip and fall, two football players colliding helmet to helmet.

Saffron promotes apoptosis and inhibits growth of cancerous cells

New research suggests that saffron provides a significant chemopreventive effect against liver cancer in animal models. When saffron was administered to rats with diethylnitrosamine (DEN)-induced liver cancer an inhibition of cell proliferation and stimulation of apoptosis was observed. Full findings appear in the September issue of Hepatology, a journal published by Wiley Blackwell on behalf of the American Association for the Study of Liver Diseases.

Risk of depression in formerly depressed people

Depression is increasingly recognized as an illness that strikes repeatedly over the lifespan, creating cycles of relapse and recovery. This sobering knowledge has prompted researchers to search for markers of relapse risk in people who have recovered from depression. A new paper published in Elsevier's Biological Psychiatry suggests that when formerly depressed people experience mild states of sadness, the nature of their brains' response can predict whether or not they will become depressed again.

No effective treatment yet for acute lung injury

Patients can essentially drown in their own fluids when trauma and infection prompt blood vessels to leak, flooding millions of air sacs in their lungs.

ATGL produces key signaling molecules essential for regulation of lipid, energy metabolism

Obesity, diabetes, and cardiovascular diseases are daunting modern-day epidemics. In Western Europe more than 50% of the population is overweight and approximately 15 million people die from cardiovascular diseases such as heart attacks and stroke every year. These conditions are often caused by disorders of fat metabolism, resulting in a massive accumulation of fat in various tissues and of cholesterol in the walls of arteries.

Insights into how ruminations are represented in the brains of depressed persons

All of us, at times, ruminate or brood on a problem in order to make the best possible decision in a complex situation. But sometimes, rumination becomes unproductive or even detrimental to making good life choices. Such is the case in depression, where non-productive ruminations are a common and distressing symptom of the disorder.

NIH bias against African-Americans confirmed

Black scientists are significantly less likely than white scientists to win grants from the National Institutes of Health, according to an audit released Thursday. This confirmed suspicions inside the agency about a lingering bias against African-Americans.

Micro-organisms hide themselves from immune defences

That micro-organisms have a great capacity to vary their surface structure is well known. It is one of the reasons why it is so difficult to develop vaccines against HIV and malaria, and why new influenza vaccines have to be produced every year. But it seems that these micro-organisms are also able to completely avoid activating a strong immune response in the person attacked.

Tiny molecule could bind to B cell EB12 receptor and prevent cancer

Infection with Epstein Barr means that the B cells, which are the primary memory cells of the immune system, are hi-jacked. When the virus has penetrated, researchers observe an excess of a special bio-antenna, a receptor known as EB12, suddenly sprouting from the surface of the B cells. But why they do so remains a mystery.

Research uncovers natural defense mechanism that inactivates C. diff toxins

Groundbreaking research encompassing Case Western Reserve University School of Medicine and University Hospitals Case Medical Center, has uncovered a natural defense mechanism that is capable of inactivating the toxin that spreads Clostridium difficile, or C. diff, an increasingly common bacterial infection in hospitals and long-term care settings.
